FB, Comp, CS --0.3 V to 6 V ........................................ Power Disispation SO-8 1 W ........................................ Power Disispation TSSOP-8 830 mW ................................ StorageTemperature --55 to 150_C .................................. Currents are positive into, negative out of the specificed terminal. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. RECOMMENDED OPERATING RANGE Input Voltage SiP2803/5 5 to 11 V .................................... Input Voltage SiP2800/1/2/4 6 to 11 V ................................ Operating Temperature Range --40 to 85_C ...........................
